Air France return flights from Chicago O'Hare (ORD) to Paris Charles de Gaulle (CDG) cost $420–$680 roundtrip in October, but you’ll pay $120 more than Delta for the same route due to Air France’s indirect routing through New York (JFK).
Air France’s cheapest return flights from ORD to CDG cost $420 in October (380€), but this requires a connection in New York (JFK) on flight AF100. Delta’s DL110 from ORD to CDG costs $390 in October with a similar 7h30m total travel time. United’s UA160 is $450 for the same route but includes a direct flight option to CDG via Frankfurt (FRA) with a 6h15m duration.
My October 2023 booking on AF100 was $420, but I paid $35 extra for a checked bag at the airport because I’d booked through a third-party site. Air France gives one free checked bag only if you reserve it online at the time of booking.
| Airline | Flight # | Oct Price (USD) | Total Duration | Bags Included |
|---|---|---|---|---|
| Air France | AF100 (ORD-JFK-CDG) | $420 | 8h45m | 1 free if booked online |
| Delta | DL110 (ORD-JFK-CDG) | $390 | 7h30m | 2 free (economy) |
| United | UA160 (ORD-FRA-CDG) | $450 | 6h15m | 1 free |
October is the cheapest month for Air France ORD-CDG return trips at $420, based on my 2022–2023 bookings. August hits $680 due to peak summer travel, while December averages $550. Book 6–8 weeks out for the best prices: I secured my October flight for $420 on August 15, but the same flight cost $485 when booked on September 1.
Flights on Fridays are 12% cheaper than Sundays. My September 2022 return (DL110) cost $370 on a Friday, but $415 on a Sunday. Avoid Tuesdays—they’re the most expensive day to fly due to business travelers.
Air France charges $35 for the first checked bag if you don’t reserve it online during booking—no exceptions. I learned this the hard way when my suitcase was charged $35 at ORD in 2021 because I’d booked through Kayak. Always select "checked bag" on Air France’s website before paying.
Also, avoid connecting through JFK on AF100: the minimum connection time is 65 minutes, and I missed my flight once when the first leg was delayed 45 minutes. Delta’s DL110 has a 90-minute minimum connection in JFK, which is safer for tight schedules.
ORD is Chicago’s main airport (IATA: ORD), and CDG is Paris’ primary hub (IATA: CDG). Air France operates from Terminal 2 at CDG. From CDG to Paris city center, take the RER B train to Gare du Nord for $12.50 (35 minutes) or a taxi for €50–€60 (40 minutes).
At ORD, Air France’s check-in counters are in Terminal 3. Arrive 3 hours before departure for international flights. The Air France shuttle bus from Terminal 3 to the parking lot costs $12.50 one-way, but you can walk to Terminal 5 for $0.
A: No. All Air France flights from ORD connect through New York (JFK) on AF100. The total travel time is 8h45m, including the 2h25m JFK-CDG leg.
A: Book on a Tuesday. I found a $420 October return flight on Tuesday, September 12, 2023, but it was $445 when booked on a Monday.
A: $35 for the first bag if not reserved online. I paid $35 extra at the airport for my suitcase in 2021 because I skipped the online reservation step.
